Fig. 14.3 A comparison of the effect of ring geometry and charge size on ring velocity. The height and thickness of the ring was varied from 1 to
2 mm and the charge radius was varied from 6 to 9 mm

Fig. 14.4 A study of the effect of a gap between the copper tube and the driver, explosive radius, and copper tube thicknesses. The dimensions
are in mm. The ring cross-section was fixed at 1.5 mm × 1.5 mm square. The charge height was fixed at 20 mm
